Ext3 for large filesystemsExt3 for large filesystemsPosted Mar 20, 2007 16:32 UTC (Tue) by BrucePerens (subscriber, #2510)In reply to: Ext3 for large filesystems by sandeen Parent article: Ext3 for large filesystems Not too long ago, Unix systems replaced seek() with the lseek(), and were able to handle longer offsets even though they were 16-bit machines. The word width of your CPU in no way limits the width of words upon which you can perform arithmetic. The new 48-bit field is not using compiler types wider than 32 bits for its implementation. They could use "long long", but I suppose that's less portable. Bruce
